DISK-SLED.

Specification of Letters Patent.

Patented Sept. 6, 1 91 0.

Application filed March 28, 1910. Serial No. 551,866.

To all whom it may concern:

Be it known that I, FLOYD E. CHAMBER- LIN, a citizen of the UnitedStates, residing at Schaller, in the county of Sac, State of Iowa, haveinvented certain new and useful Improvements in Disk -Sleds; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to sleds used in carrying disk plows to and fromthe field and has for its principal object to provide a sled which maybe hooked to the plow draft pole so that the draft animals need not beremoved from the plow.

The novelty of this invention resides in the construction andarrangement of the cleats which hold the disk plow in position on thesled.

In the accompanying drawing forming part of this specification, Figure 1is a side elevation of a disk carrying sled constructed in accordancewith my invention and showing a disk plow thereon. Fig. 2 is a plan viewof the sled. Fig. 3 is a longitudinal sectional view of the sled.

Referring now to the drawings, in which like characters of referencedesignate similar parts in the views shown, 10 and 11 designate a pairof substantially rectangular timbers which constitute the runners of thesled. These timbers may be shod with metal if desired to protect theirwear surfaces. The forward bottom corner of each runner is cut away asshown at 12 to provide an inclined surface to guide the runners overobstructions, and the rear uppercorner of each runner is cut away asshown at 13 to provide an inclined seat for the rear cleat. Arrangedtransversely upon the top faces of the runners are a pair of cleats 1 1and 15 which will be hereinafter referred to as the rear and forwardcleats respectively. Each cleat is preferably formed from a rectangulartimber and has its top face rounded as shown at 16. Countersinks 17 areformed in the top faces 16 of the cleats to house the heads of bolts 18which pass through the cleats and runners and are provided with nuts 19which bear against the top faces of countersinks 20 formed in the bottomfaces of the runners. The rear cleat 14 is arranged on the inclinedportions 13 of the runners with its rounded top face disposed rearwardlyas shown to provide a sloping. surface over which the disks may pass inadvancing into engagement with the top faces of the runners beyond theforward face of the cleat. The forward cleat 15 is spaced from the rearcleat a distance approximately equal to the diameters of the disks andis arranged with its curved top face sloping toward the forward ends ofthe runners so as to provide an inclined surface over which the disksmay advance when leaving the sled. It is now clear that the draft.animals may be driven over the sled until the disks have dropped intothe space between the cleats in which position the sled may be hooked tothe draft pole as will presently be described and the plow transportedto its destination without unhitching the draft animals. When it isdesired to remove the plow from the sled, the latter is unhooked fromthe draft pole, and the disks elevated so as to clear the rear face ofthe forward cleat when the animals are driven forward, thus advancingthe plow off from the sled.

A braceplank 21 is bolted transversely of the top faces of the runnersin advance of the forward cleat. The securing bolts 22 which secure theplank to the runners have their heads countersunk in the plank as shownat 23 and their retaining nuts countersunk in the bottom faces of therunners as shown at 24.

For hooking the sled to the plow draft pole the following constructionis employed: secured to the forward end of each runner is a clevis 25formed in the usual manner from a single strap of metal bent U shapedand having its terminals provided with eyes which receive a bolt 26passed transversely through the side faces of the runner. Projectingforwardly from the clevises are links 27 and 28 each having at oneextremity an eye 29 loosely engaging the clevis and at its oppositeextremity a bill 30 bent at right angles or substantially so to the bodyof the link. An eye bolt 31 is secured to the draft tongue with its eyedepending from the bottom face of the tongue as shown. This eye bolt isso positioned on the tongue that the hills of the hooks 27 will registerwith the eye when the disks are engaged between the cleats 14 and 15. Itis now clear that when the draft animals are halted after the disks havedropped between the cleats, the hooks may be easily engaged in the eyebolt, after which the animals may be started and the sled and plowtransported to the field as will be readily understood.

It will be seen that since the bolt heads and retaining nuts arecountersunk in the runners and cleats that there will be no 0bstructionoffered to the sled moving easily over the ground nor to the disksadvancing upon or off from the cleats. It will be further noted that byvirtue of the rear cleat being seated on inclined surfaces, that therewill be less tendency for the sled to slipforwardly when the disksengage the rearmost part of the cleat than were-the cleat arranged uponhorizontal surfaces.

From the foregoing description taken in connection with the accompanyingdrawing, it is thought that the construction and operation of myinvention will be easily understood, it being understood that variouschanges in the form, proportion and minor details of construction may bemade within the scope of the appendedclaim.

hat is claimed is A sled comprising runners having their rear uppercorners cut away to provide inclined seats, a cleat secured transverselyupon said seats and having its top face slop-- ing rearwardly, a cleatsecured transversely on the runners in advance of the first-named cleatand having its top face sloping for wardly, and hooks pivotallyconnected to the forward ends of the runners and having their billsengageable with a draft pole.

In testimony whereof, I affix my signature, in presence of twowitnesses.
